Question 196544: The diameter of a large circle is twice that of the small circle which is inside the large one. How many rotations will the small circle make in rolling without slipping on the inside of the large circle and also on the outside of the large circle? Found 2 solutions by edjones, Alan3354:Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! Let the diameter of the large circle be 2d. The circumference is 2pi*d
The circumference of the small circle is pi*d so it would have to make 2 rotations inside or outside the circle (since the length of the circumference is the same inside or outside the circle).
